Application 01
SAGD produced water recovery
Vacuum membrane distillation handles the high silica, high TDS, and dissolved hydrocarbons that crash RO trains.

Oil, Gas & Energy
plants and separation, end to end.
We fabricate the equipment and the plants that oil, gas, and energy operators run on, and we bring our own membrane IP for the streams that defeat conventional separation. Pressure vessels, separators, slug catchers, gas-processing skids, and full packaged units, built in our shops, ASME / API code-stamped where required. Where the fluid is hard, we add patented membrane systems for produced water, frac flowback, glycol regeneration, amine reclamation, and BTEX recovery, across upstream production, midstream processing, LNG and gas processing, and refineries.
What you get
Outcomes our customers see.
Specific to oil, gas & energy. Verified on real projects. The numbers below come from work we have shipped, not data sheets.
- Recovery on tested SAGD produced water
- 96%
- From a 15% TDS feed that pinned evaporators on energy cost.
- Solvent recovery from natural gas processing
- 99.5%
- Pervaporation systems that pay back in 18 to 24 months on solvent savings alone.
- Footprint vs evaporator-based recovery
- 1/3
- Skid-mounted units that fit existing facility envelopes without civil works.
- Disposal cost reduction
- 70 to 90%
- Closing the loop on produced water turns a per-barrel disposal cost into a recovered-water credit.
Field-measured results
Frackwater lab data, three feeds.
Real samples, real numbers. Recoveries and permeate quality measured on commissioned AQUA-SEP runs against three named feed sources. Source: Petro Sep General Presentation, 2024.
| Feed source | Feed salt (TDS) | Permeate salt | Water recovered |
|---|---|---|---|
| Marcellus | 2.4% | 0.001% (10 ppm) | 90% |
| Texas | 8.1% | 23 ppm | 88% |
| Western Canada | 13.8% | 7 ppm | 80% |
Each row is a real frackwater sample tested on a Petro Sep AQUA-SEP membrane train. The numbers are reproducible on a representative sample from your operation: ship us a sealed container, we will return characterized recovery and permeate-quality data inside two to six weeks.

What we deliver.
The specific scopes and separation problems we solve for oil, gas & energy operators.
Application 02
Frac flowback treatment
On-site treatment of mixed brines and hydrocarbons for reuse in the next stage or compliant discharge.
Application 03
Natural gas glycol regeneration
Pervaporation removes water from glycol streams without the energy cost of conventional reboilers.
Application 04
Sour water and amine reclamation
Membrane-based separation of degradation products and heat-stable salts that conventional distillation cannot remove.
Application 05
BTEX and VOC capture
Recovery of valuable volatile organics from aqueous streams, in compliance with state and provincial limits.
Fabrication scope
What we build for this sector.
Most oil and gas projects start with a fabrication scope: separators, columns, slug catchers, gas-processing skids, or a packaged unit. Our shops handle ASME U, U2 & R and API code-stamped pressure equipment, sour-service materials, and full skid packaging. PSE Malaysia recently delivered two Acid Gas Oxidizer (AGO) STACK units, each 40 metres long.

Membrane technologies
The right process for the fluid.
Oil and gas streams almost never look like a single problem. We pair technologies, often combining VMD on the water side with pervaporation on the hydrocarbon side, to deliver a turnkey system rather than a single unit.
VMD
Vacuum Membrane Distillation
High-recovery treatment for high-salinity and complex feeds where reverse osmosis cannot go.
Learn more
PV
Pervaporation
Selective separation of liquid mixtures, including the azeotropes that distillation cannot break.
Learn more
VP
Vapor Permeation
Vapor-phase separation for solvent dehydration and VOC recovery in chemical and pharmaceutical operations.
Learn more
ZLD
Zero Liquid Discharge
Closed-loop systems that recover water and isolate solids for industrial wastewater.
